To all whom t may concern Be it known that- I, JAMES N'. BRADLEY,

aicitizen of the United States, residing at- Idaho Springs, in the county of Clear Creek and State of Colorado, have invented certain new and useful Yin Auto-Locks,

particularly tolocks for automobiles,trucks and motorcycles, and `has for itsobject to provide a lock including a valve which may be turned into and out of position to closel the supply to the motor, thel lock being only operable by a key of a specific nature. e

A special object of the invention is to produce a lock of this kind whichV will be V`simple and whichmay .be easily'as'sembled,

thus ticle. v

Other objects and advantages will be apfparentfrom the following description, but it will be understood vthat changes in the'specific structure shown .and described may be made within the scope of the claims, with outdeparting from the. spirit of the invention.

tending fiat bar 14, which may thus be of diametrically opposite threaded openings 15, and within the lower end of the tube there is a seat 17 in its lower surface, and'having a reduced central stem passage 18 in its upper Patented Apr. 22,1913. Application led Maren-28, 1911.v Serial No. 617,470. i y v block 16,having a valve seat face communicating with the valve seat.

lD iametrically oppositej.jpassages 19 are formed in the block '16 and communicate with the valve seat,.these passages having their outer ends enlarged, as shown at 20,

and interiorly threaded, these threaded en' largements registering with the openingsI 15. A pair of pipe nipples 21 are screwed into 15 and into -the enlargements ositely beyond the thereof, and holdposition. Disposed in the seat '17 is a turn-plug valve 22, having a passageL 23 which may be broughtinto reg; straton with the two openings 19, thus connecting t-he nipples Afor the 'passage of fluid therethrough, and this valve has a bi-` furcated and receiving'the lo-w between .it furcatibns screwed upon the lower end of the tube and holds the'valve in posit-ion. A washer tube 6 at the lower en stem l24 lying in the passage 18,

er end of the bar 14'80 A cap plate '25 is 27 may be used if necessary to prevent leak- -v age. It is ofcourse understood that each of the nipples is the supply line tothe motor.

In use, the structure is located in a conpreferably within easy reach 'of the'drivrs seat, and, as will be understood, the valve may be turned and' locked in closedI position when the car is not y In Fig. 5 there is shown a different form of the invention in whichl the revoluble member 13 of the lock element may beused tuous type, "as indicated in the small detail, 5A. This slot receives a liuted key, as will be provided with a union 28, by a means of which the device isconnected with "i understood, andthe revoluble member 13 of the lock element terminates short of ythe lower end of the barrel extension 9, to leave a vspace B therebelow. The bar 14 has a 'flanged upperrend C lying in the space B and, adjacent to its lower end, has'a lateral pin D, beneath which there is engaged a helical spring E,` which rests against the upper face of the block 16, and thus holds the bar 14 normally raised and with its lower end disengaged from between the fur#- cations of the stem 24.5 In this form of the .45 provided with the cent-ral boss 30, termiinvention, the passage 18 is extended above the stem 24, as shown at F, and .thus acts as a guide for the bar 14, this bar being provided with a second transverse pin H,

which lies within the extension and prevents y lateral movement of the bar in the plane of its short dimension. The space B is of such length that, when 'the flanged end C of t e bar is against the lower end of the revo-V luble member, the lower end of the bar is in the portion of the passage 18. The upper .end of thev bar 14 has a slot G therein, to`

receive the lower end of the keyfor rotation of the bar-therein. From the foregoing it will be seen that when the key is inserted, it will engage,the upper end of the bar, and,

l upon -urther introduction of the key, thev v bar will be forced down to engage the valve, when rotation of the key will open or close thevalveas the case may be. In this form K of the invention it will be .seenY that it will 33 having on its inner end a point 34 adapted to engage the boss 30 l'to vertically adjust the valve to its seat and provide a yclose joint. f l

In the form shown in Fig. 7 there is screwed on to the end of thetube 6 a lcasing 2 comprising a tubular tapered body 'portion 40 and. extending'in opposite directions from 36 4in 'which is seated a turn-plug valve 37 the sides of the body portion are the nip' 7 ples 38 for connection` with the pipe.

lower' portion of thel valve is similar to that shown in Fig', 2, its bottom portion, being natin'g" a short distance above the lower threaded end ofthe body portionof-'the casadjusting -plug 33'..

ing.v A capy 25" is screwed on to the lower end f the casing, and is provided with a threa ed opening to receive the threaded The upper end of the turn-plug is providedwith a bifurcatedtcentral lug to recive'the lower end; of the bar 14'as in the other forms:
